240 MR. W. P. PYCEAFT ON THE 



its arms extend outwards on to the axillai-y memhrane, bet\yeen the x>t- liumeralis and 

 the scapula. Stem forked posteriorly, so as to embrace Imt not surround the oil-gland. 



Ft. ventral is.— Outer branch very strong, arising low down, over the dorsal third of 

 the furculum. 



Median branch narrower and more sharply defined than in B. maximus, extending 

 backwards to the level of the posterior third of the carina sterni. Not recurved at its 

 posterior end, where it passes into the " hook." 



Inner branch arising from the median rather about its middle ; more sharply defined 

 than m B. maxlmus. 

 Pt. alaris : — 



Bemiges. — Metacarpo-digitals 11 ; cubitals 19. 

 Tectrices : — 



T. majores. — The dorsal major coverts of the cubital remiges liaving the 5th slightly 

 shorter than 4th, ))ut longer than the 6tli. 5th and 7th equal. 



T. medi(B. — 1-5 longest in the row ; 6 abruptly shorter than 5 ; from 6 inwards 

 gradually increasing in length. 



T. minores. — The same remarks apply to these feathers as to the t. medicB. There are 

 three rows of minor coverts. 



Pf.femoralis. — IFemoro-crural band terminating below the knee. 



Pt. cruralis. — Toes bare, but beset with stumps of old feathers worn down to surface 

 of skin. Terminal phalanx having the base covered with scales. 



Bubo toequatus, Daud. {Syrnium iJerspicillatum, Lath., of Sharpe's Catalogue, p. 277.) 



Pt. capitis : — 



Pronto- parietal are a. — Frontal area in the form of a broad well-defined band, 

 rapidly expanding above and rather behind the eyes to merge with the parietal area. 



Loreal area. — Ill-defined. 



Inter ramal area expanding in the region of the gape to join the ramal area, 

 which does not extend backwards to the end of the jaw. 



Periphery of the disc ill-defined. 



Pt. colli laterale. — As in Bubo. 



Pt. colli dorsalis. — Lateral neck-folds very slight, tract narrow. 



Pt. colli ventralis. — Divides about halfway down the neck. 



Pt. spinalis. — Interscapular fork arising in the upper third of the interscapular region ; 

 arms narrow, extending to the level of the end of the scapula. Branches of the lumbar 

 fork arising near the anterior border of the ilium ; short, running out on to the axillary 

 membrane. 



Pt. ce^itralis. — Outer branch well defined, arising at the summit of the shoulders ; 

 median long, narrow, not curved terminally (as in Syrniuni) ; inner branch broad, 

 sharply defined from the median, and, rising near tlie summit of the shoulder, joins its 

 fellow of the other side just in front of the cloacal aperture. 



Pt. femo)'alis. — Pemoro-crural tract terminating at the knee-joint.
